본 발명은 자동 변속기의 리어 커버(rear cover) 어셈블리에 관한 것으로, 더욱 상세하게는 제작 공정이 감소된 리어 커버에 관한 것이다. The present invention relates to a rear cover assembly of an automatic transmission, and more particularly to a rear cover with reduced manufacturing process.

주지하는 바와 같이 자동 변속기의 리어 커버 어셈블리는 자동 변속기의 뒷부분에 자동 변속기의 구동축을 지지하도록 배치되는 차량의 부품이다. As is well known, the rear cover assembly of the automatic transmission is a part of the vehicle arranged to support the drive shaft of the automatic transmission at the rear of the automatic transmission.

도1은 종래기술에 의한 자동 변속기의 리어 커버 어셈블리(rear cover assembly)를 보여주는 도면이다. 1 is a view showing a rear cover assembly (rear cover assembly) of the automatic transmission according to the prior art.

도1을 참조하면, 리어 커버 어셈블리는 리어 커버(rear cover)(101), 슬리브(sleeve)(103), 실링(seal ring)(105), 베어링(bearing)(109), 리테이너(retainer)(도시되지 아니함) 및 코킹부(calking portion)(107)를 포함한다. Referring to Fig. 1, the rear cover assembly includes a rear cover 101, a sleeve 103, a seal ring 105, a bearing 109, and a retainer ( Not shown) and a caulking portion 107.

슬리브(103)는 실링(105)과 리어 커버(101)의 사이 또는 실링(105)과 리테이너 사이에서 마모가 발생되지 아니하도록 배치된다. The sleeve 103 is arranged so that no wear occurs between the seal 105 and the rear cover 101 or between the seal 105 and the retainer.

실링(105)은 자동 변속기의 작동에 이용되는 오일이 누출되지 아니하도록 배치되며, 베어링(109)에는 자동 변속기의 구동축이 회전 가능하도록 접촉된다. The sealing 105 is disposed so that oil used for the operation of the automatic transmission does not leak, and the bearing 109 is in contact with the drive shaft of the automatic transmission so as to be rotatable.

슬리브(103), 실링(105), 베어링(109) 및 리테이너는 당업자에게 자명하므로 상세한 설명은 생략한다. The sleeve 103, the sealing 105, the bearing 109 and the retainer will be apparent to those skilled in the art, so detailed description thereof will be omitted.

슬리브(103)가 회전할 경우, 유로(도시되지 아니함)가 차단되므로 자동 변속기의 작동이 정지 될 수 있다. When the sleeve 103 rotates, the flow path (not shown) is blocked, so that the operation of the automatic transmission may be stopped.

따라서, 슬리브(103)의 회전을 방지하기 위하여 코킹부(107)가 형성된다. Thus, a caulking portion 107 is formed to prevent rotation of the sleeve 103.

그런데, 코킹부(107)가 형성되기 위해서는 슬리브(103)의 홈(120)이 제작되어야 하고, 리어 커버(101)의 일부가 슬리브(103)의 홈(120)에 삽입되어야 하므로 제작 공정이 복잡해지고 제작시간이 길어지는 문제가 있었다. However, in order to form the caulking portion 107, the groove 120 of the sleeve 103 must be manufactured, and since a part of the rear cover 101 must be inserted into the groove 120 of the sleeve 103, the manufacturing process is complicated. There was a problem that the production time is longer.

따라서, 본 발명의 목적은 제작 공정이 단순한 리어 커버 어셈블리(rear cover assembly)를 제공하는 것이다. It is therefore an object of the present invention to provide a rear cover assembly with a simple manufacturing process.

상기 목적을 달성하기 위하여 본 발명에 의한자동 변속기의 구동축을 지지하는 리어 커버 어셈블리(rear cover assembly)는 상기 구동축이 회전 가능하도록 지지하는 베어링이 배치되는 리어 커버(rear cover), 상기 리어 커버에 고정되도록 타원형으로 형성된 슬리브(sleeve), 및 오일이 누출되지 아니하도록 상기 슬리브에 배치되는 실링(seal ring)을 포함한다. In order to achieve the above object, a rear cover assembly for supporting a drive shaft of an automatic transmission according to the present invention is fixed to a rear cover and a rear cover in which a bearing for supporting the drive shaft is rotatable is arranged. A sleeve formed as elliptical as possible, and a seal ring disposed on the sleeve to prevent oil from leaking.

상기 슬리브의 직경의 비율은 긴 직경과 짧은 직경의 비율이 21:20 으로 실현될 수 있다. The ratio of the diameter of the sleeve can be realized 21:20 ratio of the long diameter and the short diameter.

상기 슬리브는 상기 리어 커버에 압입됨으로써 고정될 수 있다. The sleeve may be fixed by pressing in the rear cover.

이하, 본 발명의 실시예를 첨부된 도면을 참조로 상세히 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도2는 본 발명의 실시예에 의한 자동 변속기의 리어 커버 어셈블리를 보여주는 사 시도이고, 도3은 본 발명의 실시예에 의한 자동 변속기의 리어 커버 어셈블리를 보여주는 도면이다. 2 is a view showing a rear cover assembly of an automatic transmission according to an embodiment of the present invention, and FIG. 3 is a view showing a rear cover assembly of an automatic transmission according to an embodiment of the present invention.

도2 및 도3을 참조하면, 본 발명의 실시예에 의한 자동 변속기의 구동축을 지지하는 리어 커버 어셈블리(rear cover assembly)는 리어 커버(rear cover)(201), 슬리브(sleeve)(203), 및 실링(seal ring)(205)를 포함한다. 2 and 3, a rear cover assembly supporting a drive shaft of an automatic transmission according to an embodiment of the present invention includes a rear cover 201, a sleeve 203, And a seal ring 205.

리어 커버(201)에는 구동축이 회전 가능하도록 지지하는 베어링(bearing)(109)이 배치되며, 슬리브(203)는 리어 커버(201)에 고정되도록 타원형으로 형성된다. The rear cover 201 is provided with a bearing 109 for rotatably supporting the drive shaft, and the sleeve 203 is formed in an elliptical shape to be fixed to the rear cover 201.

실링(105)은 자동 변속기를 작동시키는 오일이 누출되지 아니하도록 슬리브(203)에 배치된다.The seal 105 is arranged in the sleeve 203 so that the oil for operating the automatic transmission does not leak.

일반적으로 자동 변속기에는 엔진으로부터 동력이 전달되는 구동축이 배치되며, 상기 구동축은 본 발명의 실시예에 의한 베어링(109)에 의하여 지지된다. In general, the automatic transmission is disposed with a drive shaft for transmitting power from the engine, the drive shaft is supported by a bearing 109 according to an embodiment of the present invention.

즉, 리어 커버(201)에 배치되는 베어링(109)에 자동 변속기의 구동축의 일단이 배치된다. That is, one end of the drive shaft of the automatic transmission is disposed in the bearing 109 disposed on the rear cover 201.

또한, 슬리브(203)는 리테이너(retainer)(도시되지 아니함), 실링(105), 및 리어 커버(201)가 마모되지 아니하도록 리테이너와 실링(105)의 사이 또는 실링(105)과 리어 커버(201)의 사이에 배치된다. In addition, the sleeve 203 is provided between the retainer and the seal 105 or between the seal 105 and the rear cover (not shown) so that the retainer (not shown), the seal 105, and the rear cover 201 are not worn. 201).

리테이너는 자동 변속기 내부에서 회전하는 회전체로서 이에 대한 내용은 당업자에게 자명하므로 여기서는 그 상세한 설명은 생략한다. The retainer is a rotating body that rotates inside the automatic transmission, and details thereof will be apparent to those skilled in the art, and thus a detailed description thereof will be omitted.

슬리브(203)가 회전하는 경우, 도2에 도시된 바와 같이, 유로(111)가 차단되므로 자동 변속기의 작동이 정지된다. 즉, 슬리브(203)가 회전하면 변속이 이루어지지 아니한다. When the sleeve 203 is rotated, as shown in Fig. 2, the flow path 111 is blocked, so that the operation of the automatic transmission is stopped. That is, when the sleeve 203 rotates, shifting is not made.

따라서, 슬리브(203)가 타원형으로 형성됨으로써, 슬리브(203)는 리어 커버(201)에 고정된다.Thus, the sleeve 203 is formed in an elliptical shape, whereby the sleeve 203 is fixed to the rear cover 201.

슬리브(203)가 타원형으로 형성되기 때문에 슬리브(203)는 리어 커버(201)에 대하여 상대적으로 회전하지 아니한다. Since the sleeve 203 is formed elliptical, the sleeve 203 does not rotate relative to the rear cover 201.

따라서, 도3에 도시된 바와 같이, 본 발명의 실시예에 의한 리어 커버 어셈블리는 리어 커버(201)와 슬리브(203)을 고정하기 위한 코킹부를 포함하지 아니한다. 그러므로, 슬리브(203) 및 리어 커버(201)의 제작 공정이 단순해질 수 있으며, 제작 시간이 단축될 수 있다. Thus, as shown in Figure 3, the rear cover assembly according to the embodiment of the present invention does not include a caulking portion for fixing the rear cover 201 and the sleeve 203. Therefore, the manufacturing process of the sleeve 203 and the rear cover 201 can be simplified, and the manufacturing time can be shortened.

도4는 본 발명의 실시예에 의한 자동 변속기의 리어 커버 어셈블리의 슬리브(sleeve)의 모양을 보여주는 도면이다. 4 is a view showing the shape of the sleeve (sleeve) of the rear cover assembly of the automatic transmission according to an embodiment of the present invention.

타원의 직경의 비율, 즉, 슬리브(203)의 긴 직경과 짧은 직경의 비율은 21:20 로 실현될 수 있으나 이에 한정하지 아니한다. The ratio of the diameter of the ellipse, that is, the ratio of the long diameter and the short diameter of the sleeve 203 may be realized as 21:20, but is not limited thereto.

또한, 슬리브(203)는 리어 커버(201)에 압입됨으로써 고정될 수 있다. In addition, the sleeve 203 may be fixed by being pressed into the rear cover 201.

즉, 종래 기술에 의한 슬리브의 직경과 본 발명의 실시예에 의한 슬리브(203)의 긴 직경은 동일하게 형성될 수 있다. 예를 들어, 슬리브(203)의 긴 직경은 21mm 로 형성될 수 있으며, 짧은 직경은 20mm로 형성될 수 있다. That is, the diameter of the sleeve according to the prior art and the long diameter of the sleeve 203 according to the embodiment of the present invention may be formed the same. For example, the long diameter of the sleeve 203 may be formed to 21mm, the short diameter may be formed to 20mm.

따라서, 종래 기술에 의한 리어 커버에 견고하게 압입될 수 있으며, 종래 기술에 의한 리어 커버 및 다른 구성물들이 이용될 수 있다. Thus, it can be firmly pressed into the rear cover according to the prior art, and the rear cover and other components according to the prior art can be used.

이상으로 본 발명에 관한 바람직한 실시예를 설명하였으나, 본 발명은 상기 실시예 에 한정되지 아니하며, 본 발명의 실시예로부터 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의한 용이하게 변경되어 균등하다고 인정되는 범위의 모든 변경을 포함한다.
